The recombinant human IL2Rα consists of 203 amino acids and has a predicted molecular mass of 23.3 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhIL2Rα is approximately 44 kDa due to glycosylation.

Endotoxin:

< 1.0 eu per μg of the protein as determined by the LAL method.

Stability:

Samples are stable for up to twelve months from date of receipt at -70oC.

Storage:

Store it under sterile conditions at -20oC~-70oC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
